$ gh stack --help
Stacked PRs let you break a large change into a chain of pull requests
that build on each other. Use `gh stack` to create and manage your stack
locally, then push to GitHub to create your stack of PRs.

Usage:
  gh stack [command]

Examples:
  # Start a new stack targeting your default branch
  $ gh stack init

  # Or turn an existing set of branches into a stack
  $ gh stack init --adopt branch1 branch2 branch3
